The Caravelle was in development by many several that used to work with Cloud9, it was the same team that made the MB339 and the F4, and I was supposed to be in charge of the gauges code.
After Cloud9 exited from the flight sim business, we have basically lost contact with the rest of the team, I guess they just abandoned active flight sim development, and they were in charge of the external/internal modeling, and the flight modeling.
But the real issue is, the Caravelle was a product conceived when 2D panels were still popular so it was designed to be like that. After the experience we had doing the Acceleration F/A-18 for Microsoft, which is made entirely in 3D, in case we'll ever do an airplane again, it won't be use 2D panels for sure, which means revisiting the Caravelle would mean doing it again from scratch, and that wouldn't make much sense in the current market, since with the same effort we could do a more popular and current airplane.
It won't be feasible trying to get hold of the existing work on the Caravelle and pass it to someone else, both because nobody had the rights to everything: everyone was an external contractor for Cloud9, and the only thing that belongs to FSDT, is lots of our proprietary methods to do gauges (used also in the MS F/A-18), which we wouldn't handle on the outside in any case, but rather reuse in case we'll ever do an airplane again.
EDIT: I've moved the message it the Cloud9 section.
